Get out of the car and walk where possible - I always walk to the shops (about half a mile away)
Train hard or go home - Kettlebells have helped in this regard
Eat clean food where possible - limit processed food.
limit carbs to a hand size portion on the plate and fill with protein and veggies
use fasting as a tool to break plateaus - i use leangains
If you want something to eat, eat it and then get back on it the next day. This becomes rarer the further down the line you are but its important to give your body what it wants sometimes.
